Question

Can I get the answer for those

Answer 1

Answer:

1) 5.64

2) 17.321

1) $\frac{21}{28}$

2) $\frac{16}{34}$

3) $\frac{28}{35}$

4) $\frac{32}{24}$

Step-by-step explanation:

SOH - CAH - TOA

Sin = $\frac{O}{H}$   Cos = $\frac{A}{H}$  Tan = $\frac{O}{A}$      

O = opposite, A = adjacent, H = hypotenuse

First two,  use Pythagorean Theorem

If you want to calculate the angle on the last 4, use inverse of function and put in the ratio.

For example :

1) Tan Z = $\frac{21}{28}$

   $Tan^{-1}$ ( $\frac{21}{28}$)

Z = 36.9°
